Vim command behaving differently at end of line

I have defined several maps that encaspulate a selected piece of text, e.g. to convert "text" to "\texttt{text}". This is one example for such a map:

vmap <buffer> ,t xi\texttt{<Esc>pa}<Esc>

However, this map does not work as expected when the selected text is at the end of the line. Take for example this line:

word1 word2 word3

when I execute the normal command viw,t for every word in the line, this is the result that I get:

\texttt{word1} \texttt{word2}\texttt{word3}

with a trailing space, i.e. the insert of the last texttt{ happened at the wrong place.

How can I change my map to work regardless of where it is executed?

Try

:nnoremap <buffer> ,t ciw\texttt{<C-R>"}<Esc>

You don't need to select the word first, just make sure that the cursor is on it somewhere. See :help text-objects and :help i_CTRL-R. Also :nmap would work as well as :nnoremap in this case, but :nnoremap is good practice since it prevents the RHS of the mapping triggering any nested or recursive mappings.

Try using s instead of xi. That deletes the selection and goes straight into insert mode avoiding the uncertain cursor position after deleting with x.

vmap <buffer> ,t s\texttt{<Esc>pa}<Esc>
